3. Would it be unfair to the other 19 castaways because nobody knew Russell, hence will there be a explaination of Russell by Jeff?

No its not unfair. Its just an equalizer to him. Yes, Russell is unknown to the teams, and that serves his advantage. However, he is just from Survivor:Samoa. So all the stress and exhaustion is still there. So that will negate the unfairness you think there is.

The "Survivor: Heroes vs. Villains" star who was arrested for battery in Louisiana yesterday claims the whole thing is a "misunderstanding" -- and is considering taking legal action against the cops who busted him.

A source close to Russell Hantz tells TMZ the reality star was partying near a bar he owns in Lafayette, LA Friday morning when some random partygoer told cops they saw Hantz push a woman.

We're told the alleged victim was a member of Hantz's party crew and she told cops that Hantz never touched her. But according to our source, cops told Hantz that because they had a witness statement, they were going to arrest him anyway.

We're told Hantz believes the cops mistreated him during the incident -- and now he's considering taking legal action against the arresting officers.
